Registration Statement on Form S-1 Filed December 17, 2020 File No. 333-251427 Dear Mr. Chandra: We have reviewed your registration statement and have the following comments. In some of our comments, we may ask you to provide us with information so we may better understand your disclosure. Please respond to this letter by amending your registration statement and providing the requested information. If you do not believe our comments apply to your facts and circumstances or do not believe an amendment is appropriate, please tell us why in your response. After reviewing any amendment to your registration statement and the information you provide in response to these comments, we may have additional comments. Unless we note otherwise, our references to prior comments are to comments in our December 14, 2020 letter. Registration Statement on Form S-1 Filed December 17, 2020 Shares Eligible for Future Sale, page 144 1. We note your disclosure that "[t]he shares of Class A common stock issuable upon the automatic conversion of the Convertible Notes . . . will be deemed 'restricted securities' as defined in Rule 144." However, the tables on pages 144-145 and 41-42 seem to suggest that shares of your Class A common stock issuable upon the automatic conversion of the Convertible Notes will be available for sale in the public market as of the date of your prospectus. Please revise the tables to clarify which shares of Class A common stock are available for sale as of the date of this prospectus as compared to a future date because of the restrictions contained in Rule 144, as it pertains to the shares issuable upon conversion of the Convertible Notes.
